ABSTRACT Regulation of pressure at which fluid is allowed to flow is deter- mined by a device which is externally substantially monolithic in character and includes internal components assembled within it through an end coupling. Relatively low height and small girth are promoted by unique communication of internal flow around the edge of a diaphragm from one side and which is distinctively sealed only along the opposite side. The device includes a hollow cylindrical body member, one end of which is internally threaded to serve as an inlet port connection and to receive and hold an externally-threaded insert which centrally carries a coaxial main valve, the movable stem of which is directed inwardly of the body member. The insert traps a diaphragm inside the body which is backed by a spring and edge-clamped in sealed relation with a rigid cartridge member. The exterior of the cartridge member is sealed with an interior surface of the body, but at least one passageway is afforded from the site of the main valve laterally across the diaphragm and around its outer edge and, thence, generally in an axial direction through the body member, to a downstream exit port.
